First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how changing the amount and type of food you eat affects the energy your body uses to digest and process that food. Healthy adults aged 18 to 60 will stay in a clinic for about 35 days, eating only provided meals and spending multiple 24-hour periods in a sealed room that measures their energy use. The goal is to better understand diet-induced thermogenesis, or the calories burned during digestion.
